Parker EZ-251-6MP Pneumatic Hose Coupler Male Npt Steel

Product Description

The PARKER EZ-251-6MP is a male NPT pneumatic hose coupler designed for use in industrial compressed air and pneumatic fluid systems. Built with a 0.25 inch body diameter and a 3/8-18 NPT threaded connection, this coupler provides a reliable, secure interface between air hose assemblies and pneumatic tooling or equipment. The steel construction offers durability in shop floor and production environments. It is installed by HVAC technicians, millwrights, pipefitters, and general maintenance professionals handling compressed air distribution lines.

This coupler is suited for industrial pneumatic applications where a standard 0.25 inch body size and male NPT thread are required. Typical installations include compressed air distribution headers, tool drops, and quick-connect hose assemblies in manufacturing, maintenance, and mechanical service environments. The threaded connection style allows integration into existing NPT-threaded pipe and fitting systems without special adapters.

Key Features

• 0.25 inch body diameter for standard industrial pneumatic hose coupling systems
• 3/8-18 male NPT threaded connection for direct integration with NPT pipe and fittings
• Steel construction provides strength and wear resistance in demanding shop environments
• Threaded connection type ensures a positive, leak-resistant mechanical attachment
• Single-piece packaging with a minimum order quantity of one unit

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pneumatic systems using standard 0.25 inch body couplers with 3/8-18 male NPT threaded connections.

Installation Notes

Installation is performed by qualified pipefitters, HVAC technicians, or maintenance professionals. Depressurize and bleed down the compressed air system fully before removing or installing any pneumatic fittings. Apply thread sealant tape or paste rated for compressed air service to the NPT threads before assembly. Refer to applicable facility safety procedures and compressed air system codes when working on pressurized lines.
